DynamoDB Batch Update

Question

Is there an api in dynamodb for updating a batch of items. There is an api for writing new items in batch mode (BatchWriteItem) and updating a single item using UpdateItem. But is it possible to update multiple items in one call?

Answer 1

DynamoDB does not have the batch update item currently available.

Answer 2

BatchWriteItem cannot update items. To update items, use the UpdateItem action. The BatchWriteItem operation puts or removes multiple items in one or more tables.

Answer 3

I am using DynamoDBMapper.batchSave(Iterable<? extends Object> objectsToSave) for this purpose.
